Molecular characterization of hybrid virulence plasmids in ST11-KL64 KPC-2-producing multidrug-resistant hypervirulent Klebsiella pneumoniae from China

Frontiers in Microbiology
IntroductionCarbapenem-resistant hypervirulent Klebsiella pneumoniae (CR-HvKP) strains combining virulence and multidrug resistance (MDR) features pose a great public health concern. The aim of this study is to explore the evolutionary characteristics of

Ionomycin Exhibits Potent and Selective Bactericidal Activity Against Clostridioides difficile Through Calcium‐Dependent Membrane Disruption

MicrobiologyOpen, Volume 15, Issue 2, April 2026.
Ionomycin exhibits potent and selective bactericidal activity against Clostridioides difficile, rapidly reducing vegetative cells, toxin production, sporulation, and spore germination while sparing representative gut microbiota. Its activity is calcium‐dependent and mediated through disruption of bacterial membrane potential, highlighting ionomycin as ...

Whole genome sequencing reveals significant intra-hospital clonal transmission and a potential multidrug resistant and hypervirulent sequence cluster of Corynebacterium striatum

Emerging Microbes and Infections
With increasing reports about Corynebacteritum straitum, its role as an emerging human pathogen is been recognized. However, few studies have explored the genomic epidemiology of C. straitum in China.

A Simple and Label‐Free Gold Nanoparticle Assay and Duplex PCR for Rapid Detection of Klebsiella pneumoniae K2

MicrobiologyOpen, Volume 15, Issue 2, April 2026.
A rapid, cost‐effective dual‐detection strategy for Klebsiella pneumoniae K2 was developed by combining a label‐free AuNP colorimetric assay (LOD: 1.56 ng/μL, 60 min) with duplex PCR targeting K2A and orf10 genes (LOD: 1 pg/μL). This approach enables rapid screening with accurate genetic validation for point‐of‐care diagnostics in resource‐limited ...

Rapid Emergence of an Amphibian Pathogen Coincided With Historic Amphibian Declines in the Neotropics

Diversity and Distributions, Volume 32, Issue 4, April 2026.
ABSTRACT Aim The emergence of the fungal pathogen Batrachochytrium dendrobatidis (Bd) in South America has been attributed to multiple introductions and subsequent spread in a bidirectional latitudinal wave along the primary Andean cordilleras. This is supported for Ecuador by anecdotal evidence of declines in Bd‐susceptible genera such as Telmatobius ...

Metastatic infection of hypervirulent Klebsiella pneumoniae

IDCases
Hypervirulent Klebsiella pneumoniae(hvKp) has a unique ability to cause organ or life-threatening tissue invasive infection in multiple sites. This case highlights that classical hvKp resulted in multiple abscesses in every body site, especially in the necrotizing fasciitis and osteomyelitis.

Strain, procedures, and tools for reproducible genetic transformation and genome editing of the emerging plant model Spirodela polyrhiza

New Phytologist, Volume 250, Issue 2, Page 735-756, April 2026.
Summary Duckweeds (Lemnaceae) have excellent potential for fundamental and applied research due to ease of cultivation, small size, and continuous fast clonal growth. However, their usage as model organisms and platforms for biotechnological applications is often limited by the lack of universal genetic manipulation methods necessary for transgene ...
